The response to a cholera outbreak must focus on limiting mortality and reducing the spread of the disease. It should be comprehensive and multisectoral, including epidemiology, case management, water, sanitation and hygiene, logistics, community engagement and risk communication. All efforts must b...e well coordinated to ensure a rapid and effective response across sectors.
This document provides a framework for detecting and monitoring cholera outbreaks and organizing the response. It also includes a short section linking outbreak response to both preparedness and long-term prevention activities.

In Kenya, the bacterial infections that contribute most to human disease are often those in which re-‐sistance is most evident. Examples are multidrug-‐resistant enteric bacterial pathogens such as typhoid, ... diarrhoeagenic Escherichia coli and invasive non-‐typhi salmonella, penicillin-‐resistant Streptococcus pneu-‐moniae, vancomycin-‐resistant enterococci, methicillin-‐resistant Staphylococcus aureus and multidrug-‐re-‐sistant Mycobacterium tuberculosis. Resistance to medicines commonly used to treat malaria is of particu-‐lar concern, as is the emerging resistance to anti-‐HIV drugs. Often, more expensive medicines are required to treat these infections, and this becomes a major challenge in resource-‐poor settings.

In 2015, 26% of the deaths of 5.9 million children who died before reaching their fifth birthday could have been prevented
through addressing environmental risks – a shocking missed opportunity. The prenatal and early childhood period represents
a window of particular vulnerability, where enviro...nmental hazards can lead to premature birth and other complications,
and increase lifelong disease risk including for respiratory disorders, cardiovascular disease and cancers. The environment
thus represents a major factor in children’s health, as well as a major opportunity for improvement, with effects seen in every
region of the world.

Dengue is the world’s most important arboviral disease in terms of number of people affected. Over the past 50 years, incidence increased 30-fold: there were approximately 390 million infections in 2010. Globalization, trade, travel,... demographic trends, and warming temperatures are associated with the recent spread of the primary vectors Aedes aegypti and Aedes albopictus and of dengue. Overall, models project that new geographic areas along the fringe of current geographic ranges for Aedes will become environmentally suitable for the mosquito’s lifecycle, and for dengue transmission. Many endemic countries where dengue is likely to spread further have underdeveloped health systems, increasing the substantial challenges of disease prevention and control. Control focuses on management of Aedes, although these efforts have typically had limited effectiveness in preventing outbreaks. New prevention and control efforts are needed to counter the potential consequences of climate change on the geographic range and incidence of dengue, including novel methods of vector control and dengue vaccines.

New data from the WHO reveal that an estimated 2.2 billion cases of malaria and 12.7 million deaths have been averted since 2000, but the disease remains a serious global health threat, particularly in the WHO African Region. According to WHO’s latest World malaria report, there were an estimated ...263 million cases and 597 000 malaria deaths worldwide in 2023. This represents about 11 million more cases in 2023 compared to 2022, and nearly the same number of deaths. Approximately 95% of the deaths occurred in the WHO African Region, where many at risk still lack access to the services they need to prevent, detect and treat the disease.

Mosquitoes, flies, bugs and other vectors transmit viruses, parasites and bacteria that infect millions of people globally. They cause many diseases, including malaria, dengue, leishmaniases, Chagas disease and Zika virus disease.
The World Health Organization (WHO) has developed a new strategy to... strengthen vector control worldwide. Member States welcomed this integrated approach at the 2017 World Health Assembly and adopted a resolution to support the strategy.

Each year, 33000 people die from an infection due to bacteria resistant to antibiotics. The burden of infections with bacteria resistant to antibiotics on the European population is comparable to that of influenza, tuberculosis and HIV/AIDS combined.
Human African trypanosomiasis (HAT) has been an alarming global public health issue. The disease affects mainly poor and marginalized people in low-resource settings and is caused by two subspecies of haemoflagellate parasite, Trypanosoma brucei and transmitted by tsetse flies. Progress made in HAT ...control during the past decade has prompted increasing global dialogue on its elimination and eradication. The disease is targeted by the World Health Organization (WHO) for elimination as a public health problem by 2020 and to terminate its transmission globally by 2030, along-side other Neglected Tropical Diseases (NTD). Several methods have been used to control tsetse flies and the disease transmitted by them. Old and new tools to control the disease are available with constraints.
Currently, there are no vaccines available. Efforts towards intervention to control the disease over the past decade have seen considerable progress and remarkable success with incidence dropping progressively, reversing the upward trend of reported cases. This gives credence in a real progress in its elimination. This study reviews various control measures, progress and a highlight of control issues, vector and parasite barriers that may have been hindering progress towards its elimination.

Frontline health workers (FHWs) provide services directly to communities where they are most needed, especially in remote and rural areas. Many are community health workers and midwives, though they can also include local emergency responders/paramedics, pharmacists, nurses, and doctors who serve in... community clinics.
The growing burden of non-communicable diseases (NCDs) on low- and middle-income countries threatens many health systems that are already weakened. In many countries, health systems—and health workers—are not prepared to address the complex nature of NCDs. Health systems are often fragmented, and designed to respond to single episodes of care or long-term prevention and control of infectious diseases.1 Many countries also continue to face shortages and distribution challenges of trained and supported health workers. As most NCDs are multifactorial in origin and are detected later in their evolution, health systems face significant challenges to provide early detection as well as affordable, effective, and timely treatment, particularly in underserved communities.

Psoriasis, which can involve the skin, nails and joints, is a chronic, painful, disfiguring and disabling noncommunicable disease (NCD) for which there is no cure. It negatively impacts on quality of life. Some of those who suffer from the disease develop chronic, inflammatory arthritis (psoriatic a...rthritis) that leads to joint deformations and disability. People with psoriasis are also reported to be at increased risk of developing other serious clinical conditions such as cardiovascular and other NCDs

The major neglected tropical diseases, Taenia solium taeniosis/cysticercosis and schistosomiasis caused by Schistosoma mansoni or S. haematobium are presumed to be widely distributed in Africa. Taenia solium taeniosis/ cysticercosis has been reported as an emerging disease in different regions of Af...rica [1, 2], but currently the exact distribution remains unclear. Reported prevalences of T. solium taeniosis and cysticercosis in African countries are not extensive and are further complicated by the lack of ‘gold standard’ tests for diagnosis.

WHO published guidance for clinicians and health care decision-makers on the use of corticosteroids in patients with COVID-19.
We recommend systemic corticosteroids for the treatment of patients with severe and critical COVID-19. We suggest not to use corticosteroids in the treatment of patients ...with non-severe COVID-19 as the treatment brought no benefits, and could even prove harmful. Treatment should be under supervision of a clinician.
Corticosteroids are listed in the WHO model list of essential medicines, readily available globally at a low cost. WHO encourages countries to maintain sufficient stocks of corticosteroids to treat COVID-19 and the other disease for which they are effective, while not maintaining excessive stocks which could deny other countries access.

This Interim Guidance outlines how key public health and social measures needed to reduce the risk of COVID-19 spread and the impact of the disease can be adapted for use in low capacity and humanitarian settings. The recommendations outlined here need to be adjusted to the scale of transmission, co...ntext and resources, in order to achieve the objective of managing COVID-19, namely to reduce transmission and facilitate the detection and management of infected and exposed individuals within the population. The Guidance is intended for humanitarian and development actors of all operational levels working with communities ocal authorities involved in COVID-19 preparedness and response operations in these settings, in support of national and local governments and plans. Additional considerations for support to residents of urban informal settlements and slums are available in Annex 1.

BMJ Global Health, Vol.5 No. 12Spatial subdivision of the camp (‘sectoring’) was able to ‘flatten the curve’, reducing peak infection by up to 70% and delaying peak infection by up to several months. The use of face masks coupled with the efficient isolation of infected individuals reduced t...he overall incidence of infection, and sometimes averted epidemics altogether. These interventions must be implemented quickly in order to be maximally effective. Lockdowns had only small effects on COVID-19 dynamics.
Conclusions
Agent-based models are powerful tools for forecasting the spread of disease in spatially structured and heterogeneous populations. Our findings suggest that feasible interventions can slow the spread of COVID-19 in a refugee camp setting, and provide an evidence base for camp managers planning intervention strategies. Our model can be modified to study other closed populations at risk from COVID-19 or future epidemics.

Countries, partners, and donors are committed to the global elimination of blinding trachoma by 2020.
Achieving this public health milestone requires more than funding; it requires health personnel with the
right mix of skills, and well supported and managed health systems. Mass drug administratio...n (MDA)
with Zithromax®, the Pfizer, Inc. donated antibiotic, is a key component of the SAFE strategy, endorsed
by the World Health Organization. There is growing
recognition that improving all aspects of MDA, from
planning to training, recording to reporting, and
receipt of drug to distribution (the supply chain), will
be necessary if MDA programmes are going to reduce
the community burden of Chlamydia trachomatis, and
eliminate trachoma as a cause of blindness by 2020.

Antimicrobial resistance (AMR) is an important public health concern shared by developed and developing countries. In developing countries the burden of infectious diseases is greater and exacerbated by limited access to, and availability and affordability of, antimicrobials required to treat infect...ions caused by AMR organisms. With drugs not listed on the essential drugs list (EDL), problems of increased morbidity, costs of extended hospitalisation and mortality are extremely serious. The problem of susceptibility to and spread of infections caused by multidrug-resistant (MDR) infectious agents is fuelled by factors such as limited access to clean water and sanitation to ensure personal hygiene, malnutrition, and the HIV/TB epidemic.
